Observed half-lives of H-3, Sr-90 and Cs-137 in hydrosphere in the Vltava River basin (Bohemia)
Original language description
A near field study was set up to follow the effects of the Temelín nuclear power plant construction. Reference levels of artificial radionuclides were monitored in the Vltava River upper course and its tributaries in the period 1990#2001. Monitoring continued even after the waste water release startup during the pilot operation in 2002. The assessment of the 90Sr and 137Cs concentrations histories in ground water, river bottom sediments and fish showed a decreasing trend. This trend was not influenced by the nuclear power plant pilot operation. In the case of tritium, trend of increasing concentration had been already observed since the pilot operation startup. The monitoring of changes in concentrations of artificial and natural radionuclides in influenced and uninfluenced profiles will be maintained to assess the possible influence of the operation of the Temelín nuclear power plant.
